Spices and Oils - Choose One of Each

Assuming Salt and Pepper are a given, name the one and only spice that you would want in your cupboard. Do the same for an oil of your choice.

Rather than selecting something that I'm used to, I would choose something I can't afford on a normal basis that also has multifunctional properties. And if you're an oil, I'd select something subtle enough to be used in a salad, and tough enough to have a high smoke point for roasting/sauteeing.

Extra Virgin Olive Oil is great, but it will burn with less than 300 degrees F heat. Many people are replacing avocado oil with olive oil, but it's pricier. Neverthless, if price is not an option, what would you choose?...
